I've got a nephew in Kuwait, right now
He is an MP who specializes in guarding prisoners (sorry, I don't know the technical term). His term of service was over for a number of months and he was out and pursuing a civilian career when Iraq II began. He was called back to service with promises of release in a few months. This promise has been amended several times, now. In fact the promise has devolved to "whenever we are done with you, you can go home.".
